Trait whose instances can accept a stop request and indicate whether a stop has already been requested.
This is passed in
to the run method of Suite, so that running suites of tests can be
requested to stop early.
Request that the current run stop.
Invoking this method is like pulling the stop-request chord in a streetcar. It requests a stop, but in no
way forces a stop. The running suite of tests decides when and how (and if) to respond to a stop request.
ScalaTest's style traits periodically check the stopRequested method of the passed Stopper,
and if a stop has been requested, terminates gracefully.
Indicates whether a stop has been requested.
Call this method
to determine whether a running test should stop. The run method of any Suite, or
code invoked by run, should periodically check the
stop requested function. If true,
the run method should interrupt its work and simply return.
true if a stop has been requested
